MAG X Co., Ltd. was established in December 1965 as Japan's first specialized manufacturer of plastic magnets. At the time, the raw materials and equipment needed for plastic magnet production — special resins, ferrite magnetic powder, and molding machinery — were virtually nonexistent in Japan. Working with raw material suppliers and molding equipment manufacturers, the company succeeded in creating the country's first full-scale plastic magnet (plamag). Plastic magnets are composite materials made primarily from special resin and magnetic iron oxide powder (ferrite magnetic powder), produced using various molding machines according to the intended product purpose. Over the decades, MAG X's plastic magnets found use in a wide range of fields: magnetic sheets such as those used for beginner-driver marks on cars, industrial components, advertising and signage, stationery and office supplies, novelties, and magnetic therapeutic devices. The company grew into a manufacturer with capital of 87.1 million yen and 114 employees, headquartered in Nihonbashi-Hongokucho, Chuo-ku, Tokyo, with a factory in Joso City, Ibaraki Prefecture, and a sales office in Osaka. It also expanded internationally, establishing MAGX VIETNAM LTD. in Dong Nai, Vietnam, and Shanghai MAGX Industry & Trade Co., Ltd. in Qingpu, Shanghai, China, along with affiliated companies Quick Quick Co., Ltd. and MAI International Associates Joint Stock Company in Ho Chi Minh City, Vietnam. In recent years, MAG X has continued to launch new stationery and office products, including magnetic hooks, whiteboard markers, and peelable transparent double-sided tape, and added the lifestyle goods brand plusia to its stationery/office supplies line. It won a Grand Prix at the 2026 New Year Stationery and Paper Fair. The company states it will continue to pursue technological research and development, higher-value products, new applications, and new markets as a plastic magnet pioneer.
